BEES NEST

[trishmac545]

Hi,
I am a Registered Childminder and have just come a cross a number of bees which seem to be nesting in soil in my garden. They are small and not very brightly coloured. I think they may be mining bees. There seems to be one hole in the ground which they use to enter and exit. I'm concerned as I have lots of children running around in my garden and they are alongside the pathway used by the children to gain access to the play area. Can you give me any advice on whether I can have the nest removed and relocated without harming the bees?
Thanks
